Abstract

1/1 resumo “sistema e método para determinar uma probabilidade de sucesso de poço com o uso de inversão estocástica” trata-se de um sistema e um método implantado por computador para determinar uma melhor localização de poço a partir de uma pluralidade de localizações possíveis de poço. o método inclui esboçar uma pluralidade de modelos terrestres a partir de uma distribuição posterior, em que a distribuição posterior é gerada por inversão estocástica de dados existentes; calcular uma produção de poço em uma pluralidade de localizações propostas de poço dentro de um modelo terrestre na pluralidade de modelos terrestres com o uso de uma relação entre a produção de poço e os parâmetros terrestres; calcular a partir da pluralidade de modelos terrestres, distribuições de custos com o uso da relação entre custo de poço e os parâmetros terrestres; e calcular valores ponderados de probabilidade para as localizações propostas de poço com o uso das probabilidades de inversões estocásticas dependentes de localização como pesos.1/1 abstract system and method for determining a well success probability using stochastic inversion is a computer-implemented system and method for determining the best well location from a plurality of possible locations of well. the method includes sketching a plurality of land models from a posterior distribution, wherein the posterior distribution is generated by stochastic inversion of existing data; calculating a well production at a plurality of proposed well locations within a terrestrial model in the plurality of terrestrial models using a relationship between well production and terrestrial parameters; calculate from the plurality of terrestrial models, cost distributions using the relationship between well cost and terrestrial parameters; and calculate probability-weighted values for the proposed well locations using the location-dependent stochastic inversion probabilities as weights.
